I am a HongKong Australian living in HongKong and appreciate it if veterans or users of both IB and TastyWorks, give me advice on choosing one of these brokers for trading mainly US options. I know some users of both and from what I have heard is IB 1. allow FX trades so I could buy or sell the $AUD, and 1b. get it telegraphically transferred to my local bank free once a month, whereas TW charge $45 everytime 2. TW charge a whopping $200 for 'Transfer on Death Account Transfer Fee' but is that even needed if we have a will? 3. https://www.interactivebrokers.co.u...ex=us&rgt=0&rsk=0&pm=1&rst=020204100401010801 IB says those in HKG who trade US options get portfolio margining. what is the difference between Risk-based margin, and portfolio margin? And would that make it advantageous to TW margining system? 4. I noticed that the margin costs for TW are substantially higher, will this matter for mainly short selling options with ~70K USD account? 4b. Check 'margin rates' in https://tastyworks.com/commissions-and-fees/ and compare to https://www.interactivebrokers.com/en/index.php?f=1340 which seems to offer greater than half price. Do they both offer equal rates for stock borrowing costs, when shorting? 5. customer service, TW are easily superior, in knowledge and willingness to help you understand. IB quite horrendous! 6. Heard IB liquidates quite spontaneously from forums and a user who had over 80% excess liquidity, yet had all his US options liquidated! 7. TW software is a dream compared to IB for ease in trading options I am not talking about the look, yes IB does look older, but that doesnt matter to me, its the fast, easy functionality TW has, it could look decades old, but its functionality is a dream in comparison. 8. probably most importantly, TW account holders are SIPC protected, whereas IB (HK) are not and anything you hold that is not HKG, will not be protected if the worse happens. Please share your views to help me decide. Nice if can comment on the numbered points made . Cheers Elite!
